same law, it is generally true, I believe, that south- 

 ern horses (particularly Arabian) produce most 

 female colts when united to the more vigorous 

 mares of a northern clime. 



So far as M, G. extends his comments to the 

 human race, they are not within the design of this 

 brief communication, which is intended for the 

 practical benefit of farmers. This benefit may be 

 easilj^ and plainly deducible from the above state- 

 ments so far as they relate to horses and poultry. 

 Permit me to allude to the manner in which ad- 

 vantage may be taken of both propositions in rearing 

 horned cattle. 



Suppose you have a cow that is a remarkable 

 milker, and wish to procure from her a progeny 

 with the same excellence. Now the common way 

 is, to send the cow to bull, and if she has a heifer 

 calf, it is raised with high expectations, and the 

 owner is invariably disappointed. The reason of 

 this is, as we now see, that the heifer calf partakes 

 of the external form and peculiar properties of the 

 hull and not of the cow. Proceeding then on the 

 principle developed by M, G. we should do as 

 follows : send the cow whose properties you 

 value to a bull of the ripest age and greatest vigor. 

 The product will be a hill-calf having the form 

 and inherent properties of the mother, so far 

 modified in their developements as the difference 

 of sex required, but still inherently the same. 

 This bull-calf should be carefully reared, and his 

 female progeny will exhibit the form and proper- 

 ties of his dam. 



So also if you have a bull of huge size, fine 

 form, great strength, and other excellencies, it will 

 be in vain to expect similar form and properties 

 in his immediate male progeny. IJut his heifer- 

 calves will inherit his properties, and transmit 

 them to their male progeny. Thus must we be 

 content to pass through one generation, and we 

 shall probably be well rewarded for our patience 

 and perseverance. 



It is scarcely necessary to add that such pa- 

 tience is not necessary in rearing horses. If you 

 wish to procure a colt of form and properties of 

 a fine mare, send her to a vigorous horse, and the 

 residt will probably be a male, possessing the 

 projjerties and form of the dam. On the other 

 hand, if you wish a colt resembling a celebrated 

 stud horse, you must send such a mare (either old 

 or very young) as will be most likely tp have, fi-om 

 this union, ii female foal, for it is in this crossing 

 of sexes we get the external form and properties 

 we desire. 



In conclusion allow me to express the opinion 

 that the incredulity that exists among farmers 

 about the possibility of propagating the qualities 

 of animals, may arise from their want of know- 

 ledge of these laws. " I don't believe in your 

 breeds of horses," says Farmer X. " There's my 



neighbor B. has as fine an animal as ever stepjjed, 

 that came of his old black mare that's not worth 

 a pin." Now if Farmer A. had known as much 

 as I wish to teach him by this paper, the fact he 

 stated would not have led him to his skeptical 

 conclusion. If the fine young animal was a fe- 

 male, it matters little what were the qualities of 

 the « old black mare," the foal partook of the 

 form and qualities of the sire, and so on. 



Yours, &c. B. C.

 The foregoing is a very important pa})er, and 

 the subject to which it relates is of great interest. 

 We hope it will meet that attention — that theoret- 

 ical and experimental investigation from farmers 

 and breeders of stocks which a regard to a great 

 improvement in a most essential branch of hus- 

 bandry should induce them to bestow. 



The largest hog that we have ever seen is now in 

 possession of Mr P. Mehan. It measures from 

 the snout to the extremity of the tail, eleven feet, 

 is five feet in height, and weighs 232 pounds. 

 It is remarkably well shaped, antl the flesh is of 

 extraordinary firmness, considering its isize. It 

 appears to be in perfect health, and may yet at- 

 tain a much larger growth, being not quite three 

 years old. — Dublin Journal. 



Portable Railway. — A novel machine was a 

 few days agp exhibited in the Kensington and 

 Chapham roads. It consisted of a sort of carriage 

 wheel which carries a rail road for itself, upon 

 which the carriage travels with great facility and 

 quickness. It was composed of a jointed square 

 instead of a circle, and has four rollers, not touch- 

 ing the road, and for feet which alternately come 

 to the ground, producing a kind of walking and 

 escaping obstacles. We understand that it is the 

 invention of L. Gompertz, Esq. — Rail Road

It was stated in a discourse recently delivered 

 before the members of the American Institute, 

 that there was annually consumed in the United 

 States, more silk, than all the wheat, corn, rye, 

 oats, flaxseed, biscuit, potatoes, and hops, which 

 are exported will pay for, by nearly $3,000,000 !

Being to advise or reprehend any one, consider 

 whether it ought to be in public or in private, pre- 

 sently or at some other time, also in what terms to 

 do it : and in reproving, show no signs of choler, do 

 it with sweetness or mildness. 



When a man does all he can, though it succeeds 

 not well, blame not him that did it.
